Interstellar dispersion
| Glossary Of Laser Terminology |
The velocity of propagation of electromagnetic waves depends upon frequency. thus, unless the wave is highly monochromatic, the energy in the wave arrives at the receiver at differing times. this can severely limit the modulation bandwidth, since the process of modulating data onto an electromagnetic carrier wave broadens its bandwidth.

Dispersal, английский
- Рассеяние, дисперсия; диспергирование
- The spreading of individuals away from each other, e.g., the offspring from their parents and from regions of high density to regions of low density; (analog to diffusion, as seen with the import of the potato beetle to europe). d. capacity: d. polymorphism: two or more types of dispersal structures found within a species or among the progeny of an individual. 4 4
Dispersal airfield, английский
Dispersancy, английский
Ability of an oil to disperse and suspend potential deposit-forming materials so that they can be removed from the system when the oil is drained.
Dispersant, английский
- In lubrication, a term usually used interchangeably with detergent. an additive, usually nonmetallic ("ashless"), which keeps fine particles of insoluble materials in a homogeneous solution. hence, particles are not permitted to settle out and accumulate.
- An admixture which is capable of maintaining finely ground materials in suspension; used as a slurry thinner or grinding aid.
- A dispersing agent, often of a surface active chemical, that promotes formation of a dispersion or maintains a state of dispersion by preventing settling or aggregation.
- An additive that keeps insoluble contaminants dispersed (colloidally suspended) in a lubricant, preventing the particles from settling and accumulating. dispersants help prevent the buildup of sludge, varnish and other deposits.
- A non-metallic engine oil additive that helps to prevent sludge, varnish, etc., by keeping particles suspended in a colloidal state. similar to and ordinarily used with detergents, dispersants are capable of keeping large quantities of particles in suspension, and they are ashless when burned.
Dispersant (pt), английский
A substance for promoting the formation and stabilization of dispersed particles of one substance in another.
Disperse, английский
Disperse, латинский
Disperse array, английский
Разреженный массив; разреженная матрица
Disperse dyes, английский
- A class of slightly water-soluble dyes originally introduced for dyeing acetate and usually applied from fine aqueous suspensions. disperse dyes are widely used for dyeing most of the manufactured fibers. fiber-reactive dyes: a type of water-soluble anionic dye having affinity for cellulose fibers. in the presence of alkali, they react with hydroxyl groups in the cellulose and thus are liked with the fiber. fiber-reactive dyes are relatively new dyes and are used extensively on cellulosics when bright shades are desired.
- Dyes
Disperse matrix, английский

Dispersed intelligence, английский
Распределенные средства искусственного интеллекта; распределенные логические функции
Dispersed networks, английский
Рассредоточенные сети
Dispersed operating bases, английский

Propagation, английский
- Прохождение, распространение (напр, радиоволн)
- An act of causing something to spread or multiply
- Распространение; размножение; продвижение; передача
- Распространение
- The process of distributing an index from a content index server to one or more web servers for the purposes of providing search.
- Advancement of a wave through a medium.
- Advancement of energy or a crack through a medium. see also brittle crack propagation; ductile crack propagation; fatigue crack propagation.
- Movement of a wave through a medium.7,21
Electromagnetic, английский
Monochromatic, английский
- Having a single wavelength or color. nanometer (nm)10-9 m. the average wavelength of white light is about 550 nanometers.
- A subject or image consisting of only one color in addition to any black, white, and gray tones. tip: the subtlety of the effect can be surprisingly powerful.
- The monochromatic scheme uses a single color. in most designs, a monochromatic scheme includes a combination of tints, tones, and shades from the same color family together with black, white and/or gray. to add depth and contrast.
- (homogeneous) of the same wavelength
- Light from a very small portion of the spectrum.
- Of a single wavelength or color.
Modulation, английский
- Изменение характеристик несущей в соответствии с информативным сигналом
- Модуляция
- The process, or results of the process, whereby some characteristic of one signal is varied in accordance with another signal. the modulated signal is called the carrier. the carrier may be modulated in three fundamental ways: by varying the amplitude, called amplitude modulation; by varying the frequency, called frequency modulation; by varying the phase, called phase modulation.
- The process by which some characteristic (i.e., amplitude, phase) of one rf wave is
- The process by which some characteristic (i.e., amplitude, phase) of one rf wave is varied in accordance with another wave (message signal).
- The coding of information onto a carrier frequency. may use amplitude, frequency, phase, or time, plus many forms of on/off digital coding
- The ability to superimpose an external signal on the output beam of the laser as a control.
- The process by which the characteristic of one wave (the carrier) modifies another wave (the signal). examples include amplitude modulation (am), frequency modulation (fm), and pulse-coded modulation (pcm).
- N модуляция modul|e
Modulating, английский

Intrabeam viewing, английский
The viewing condition whereby the eye is exposed to all or part of a direct laser beam or a specular reflection.
Half-power point, английский
The value on either the leading or trailing edge of a laser pulse at which the power is one-half of its maximum value.
